12018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
2Standard triple therapy for Helicobacter pylori infection in China: A meta-analysis显示文摘AIM:To assess the efficacy and safety of standard triple therapy compared with other pre-existing and new therapies in China.METHODS:Literature searches were conducted in the following databases:PubMed,EMBASE,the Cochrane Central Register of Controlled Trials,the VIP database,the China National Knowledge Infrastructure database,and the Chinese Biomedical Database.A meta-analysis of all randomized controlled trials(RCTs)comparing standard triple therapy for the eradication of Helicobacter pylori with pre-existing and new therapies in China was performed using Comprehensive Meta-Analysis 2.0.There were 49 studies that met our criteria and the qualities of these studies were assessed using the Jadad scale.The Mantel-Haenszel method was used for pooling dichotomous data.We also conducted subgroupanalyses according to age,duration of treatment and drug type.Sensitivity analyses and a cumulative metaanalysis were also performed with CMA 2.0.Publication bias was evaluated using Egger’s test,Begg’s test or a funnel plot.RESULTS:A total of 49 RCTs including 8332 patients were assessed.This meta-analysis showed that standard triple therapy with proton pump inhibitors(PPIs),amoxicillin(AMO)and clarithromycin(CLA)was inferior to sequential therapy[relative risk(RR)=0.863;95%confidence interval(CI):0.824-0.904],but was not superior to quadruple therapy(RR=1.073;95%CI:0.849-1.357)or other triple therapies(RR=1.01;95%CI:0.936-1.089).The meta-analysis also suggested that standard triple therapy is slightly more effective than dual therapy(RR=1.14;95%CI:0.99-1.31).However,the differences were not statistically significant.We removed the only trial with a regimen lasting14 d by sensitivity analysis and found that 7-d standard triple therapy was superior to 7-d dual therapy(RR=1.222;95%CI:1.021-1.461).Moreover,a sub-analysis based on the duration of quadruple therapy indicated that the 7-d and 10-d standard triple therapies were inferior to sequential therapy(RR=0.790;95%CI:0.718-0.868;RR=0.917;95%CI:0.839-1.002,respectively).Additionally,there were no significant differences in cure rate or adverse events among standard triple therapy,quadruple therapy,and other triple therapies(RR=0.940;95%CI:0.825-1.072;RR=1.081;95%CI:0.848-1.378,respectively).Standard triple therapy had a higher occurrence of side effects than sequential therapy(RR=1.283;95%CI:1.066-1.544).CONCLUSION:The eradication rates with a standard triple therapy consisting of PPI,AMO,and CLA are suboptimal in China,and new treatment agents need to be developed.Ben Wang Zhi-Fa Lv You-Hua Wang Hui Wang Xiao-Qun Liu Yong Xie Xiao-Jiang Zhou 2014World Journal of Gastroenterology2014,20,40:46
3Critical review in adsorption kinetic models显示文摘Adsorption is one of the most widely applied techniques for environmental remediation. Its kinetics are of great significance to evaluate the performance of a given adsorbent and gain insight into the underlying mechanisms. There are lots of references available concerning adsorption kinetics, and several mathematic models have been developed to describe adsorption reaction and diffusion processes. However, these models were frequently employed to fit the kinetic data in an unsuitable or improper manner. This is mainly because the boundary conditions of the associated models were, to a considerable extent, ignored for data modeling. Here we reviewed several widely-used adsorption kinetic models and paid more attention to their boundary conditions. We believe that the review is of certain significance and improvement for adsorption kinetic modeling.Hui QIU Lu LV Bing-cai PAN Qing-jian ZHANG Wei-ming ZHANG Quan-xing ZHANG 2009Journal of Zhejiang University-Science A(Applied Physics & Engineering)2009,10,5:26
4Human urokinase-type plasminogen activator gene-modifiedbone marrow-derived mesenchymal stem cells attenuateliver fibrosis in rats by down-regulating the Wnt signalingpathway显示文摘AIM: To evaluate the therapeutic effects of bone marrow-derived mesenchymal stem cells(BMSCs) with human urokinase-type plasminogen activator(u PA) on liver fibrosis, and to investigate the mechanism of gene therapy.METHODS: BMSCs transfected with adenovirusmediated human urokinase plasminogen activator(Adu PA) were transplanted into rats with CCl4-induced liver fibrosis. All rats were sacrificed after 8 wk, and their serum and liver tissue were collected for biochemical, histopathologic, and molecular analyzes. The degree of liver fibrosis was assessed by hematoxylin and eosin or Masson's staining. Western blot and quantitative reverse transcription-polymerase chain reaction were used to determine protein and m RNA expression levels.RESULTS: Serum levels of alanine aminotransferase, aminotransferase, total bilirubin, hyaluronic acid, laminin, and procollagen type Ⅲ were markedly decreased, whereas the levels of serum albumin were increased by u PA gene modified BMSCs treatment. Histopathology revealed that chronic CCl4-treatment resulted in significant fibrosis while u PA gene modified BMSCs treatment significantly reversed fibrosis. By quantitatively analysing the fibrosis area of liver tissue using Masson staining in different groups of animals, we found that model animals with CCl4-induced liver fibrosis had the largest fibrotic area(16.69% ± 1.30%), while fibrotic area was significantly decreased by BMSCs treatment(12.38% ± 2.27%) and was further reduced by u PA-BMSCs treatment(8.31% ± 1.21%). Both protein and m RNA expression of β-catenin, Wnt4 and Wnt5 a was down-regulated in liver tissues following u PA gene modified BMSCs treatment when compared with the model animals.CONCLUSION: Transplantation of u PA gene modified BMSCs suppressed liver fibrosis and ameliorated liver function and may be a new approach to treating liver fibrosis. Furthermore, treatment with u PA gene modified BMSCs also resulted in a decrease in expression of molecules of the Wnt signaling pathway.Zhi-Gang Ma Xiao-Dan Lv Ling-Ling Zhan Lan Chen Qi-Yuan Zou Ji-Qiao Xiang Jiao-Li Qin Wei-Wei Zhang Zhao-Jing Zeng Hui Jin Hai-Xing Jiang Xiao-Ping Lv 2016World Journal of Gastroenterology2016,22,6:21
5Surveillance-based evidence:elimination of schistosomiasis as a public health problem in the Peoples’Republic of China显示文摘Background:A steady progress on schistosomiasis control in the Peoples’Republic of China(P.R.China)was achieved and broadened into the twelve-year medium and long term national plan(MLNP)which marled the implementation of an integrated control strategy across all endemic areas in P.R.China in 2004.To understand the endemic trends of schistosomiasis to assess the effectiveness of an integrated strategy,we conducted an analysis of schistosomiasis surveillance data spanned from 2005 to 2015.Methods:The schistosomiasis sentinel surveillance data from sentinel sites were collected and analyzed from 2005 to 2015.In these sentinel sites,residents aged 6 years or above were screened annually by indirect hemagglutination assay(IHA),while only antibody positives were followed by stool examination either Kato-katz method(KK)and/or hatching technique(HT).Domestic animals raised in sentinel sites were examined by HT for confirming the infection of schistosomes.Snail investigation was conducted each year through systematic sampling method combined with environmental sampling method.The snails collected from field were tested by microscopic dissection method.The infection rates of schistosomes in residents,domestic animals and snails,as well as the indicators reflecting the snails’distribution were calculated and analyzed.ANOVA analysis was used to examine the changes of the number of eggs per gram feces in population and Chi-square test was used to examine any change in proportions among groups.Results:A total of 148902 residents from sentinel sites attended this study and 631676 blood samples were examined by IHA test during the 11 covered years.The annual average antibody positive rates presented a significant decrease trends,from 17.48%(95%CI:17.20–17.75%)in 2005 to 5.93%(95%CI:5.71–6.15%)(χ2=8890.47,P<0.001)in 2015.During 2005–2015,the average infection rate of schistosomes in residents declined from 2.07%(95%CI:1.96–2.17%)to 0.13%(95%CI:0.09–0.16%),accompanied by significant decrease of infection intensity in population.In 2015,the stool positives were only found in farmers,fishermen and boatmen with infection rate of 0.16%(95%CI:0.11–0.20%),0.17%(95%CI:0–0.50%)respectively.The infection rate of schistosomes in domestic animals dropped from 9.42%(538/5711,95%CI:8.66–10.18%)to 0.08%(2/2360,95%CI:0–0.20%)from 2005 to 2015.Infections were found in eight species of domestic animals at the beginning of surveillance while only two cattle were infected in 2015.Totally 98 ha of new snail habitats were found,while 94.90%(93/98)distributed in lake and marshland regions.The percentage of frames with snails decreased from 16.96%(56884/335391,95%CI:16.83–17.09%)in 2005 to 4.28%(18121/423755,95%CI:4.22–4.34%)in 2014,with a slightly increase in 2015.Meanwhile,the infection rate of schistosomes in snails was decreased from 0.26%(663/256531,95%CI:0.24–0.28%)to zero during 2005–2015.Conclusions:The infection rate of schistosomes declined significantly,providing evidence that the goal of the MLNP was achieved.Elimination of schistosomiasis as a public health problem defined as WHO was also reached in P.R.China nationwide.Surveillance-response system should be improved and strengthened to realize the final goal of schistosomiasis elimination.Jing Xu Shi-Zhu Li Li-Juan Zhang Robert Bergquist Hui Dang Qiang Wang Shan Lv Tian-Ping Wang Dan-Dan Lin Jian-Bing Liu Guang-Hui Ren Kun Yang Yang Liu Yi Dong Shi-Qing Zhang Xiao-Nong Zhou 2020Infectious Diseases of Poverty2020,9,3:20
6Sophocarpine attenuates liver fibrosis by inhibiting the TLR4 signaling pathway in rats显示文摘AIM:To explore the effect of sophocarpine on experimental liver fibrosis and the potential mechanism involved.METHODS:Sophocarpine was injected intraperitoneally in two distinct rat hepatic fibrosis models induced either by dimethylnitrosamine or bile duct ligation.Masson’s trichrome staining,Sirius red staining and hepatic hydroxyproline level were used for collagen determination.Primary hepatic stellate cells(HSCs)were isolated and treated with different concentrations of sophocarpine.Real-time reverse transcription-polymerase chain reaction was used to detect the mRNA levels of fibrotic markers and cytokines.The expression of pathway proteins was measured by Western blot.The Cell Counting Kit-8 test was used to detect the proliferation rate of activated HSCs treated with a gradient concentration of sophocarpine.RESULTS:Sophocarpine decreased serum levels of aminotransferases and total bilirubin in rats under chronic insult.Moreover,administration of sophocarpine suppressed extracellular matrix deposition and prevented the development of hepatic fibrosis.Furthermore,sophocarpine inhibited the expression ofα-smooth muscle actin(SMA),interleukin(IL)-6,transforming growth factor-β1(TGF-β1),Toll-like receptor 4(TLR4),and extracellular-related kinase(ERK)in rats.Sophocarpine also down-regulated the mRNA expression ofα-SMA,collagenⅠ,collagenⅢ,TGF-β1,IL-6,tumor necrosis factor-αand monocyte chemoattractant protein-1,and decreased protein levels of TLR4,p-ERK,p-JNK,p-P38 and p-IKK in vitro after Lipopolysaccharide induction.In addition,sophocarpine inhibited the proliferation of HSCs accompanied by a decrease in the expression of Cyclin D1.The protein level of proliferating cell nuclear antigen was decreased in activated HSCs following a gradient concentration of sophocarpine.CONCLUSION:Sophocarpine can alleviate liver fibrosis mainly by inhibiting the TLR4 pathway.Sophocarpine may be a potential chemotherapeutic agent for chronic liver diseases.Hui Qian Jian Shi Ting-Ting Fan Jiao Lv Si-Wen Chen Chun-Yan Song Zhi-Wu Zheng Wei-Fen Xie Yue-Xiang Chen 2014World Journal of Gastroenterology2014,20,7:19
7Transjugular intrahepatic portosystemic shunt vs endoscopic therapy in preventing variceal rebleeding显示文摘AIM:To compare early use of transjugular intrahepatic portosystemic shunt(TIPS) with endoscopic treatment(ET) for the prophylaxis of recurrent variceal bleeding.METHODS:In-patient data were collected from 190 patients between January 2007 and June 2010 who suffured from variceal bleeding.Patients who were older than 75 years;previously received surgical treatment or endoscopic therapy for variceal bleeding;and complicated with hepatic encephalopathy or hepatic cancer,were excluded from this research.Thirty-five cases lost to follow-up were also excluded.Retrospective analysis was done in 126 eligible cases.Among them,64 patients received TIPS(TIPS group) while 62 patients received endoscopic therapy(ET group).The relevant data were collected by patient review or telephone calls.The occurrence of rebleeding,hepatic encephalopathy or other complications,survival rateand cost of treatment were compared between the two groups.RESULTS:During the follow-up period(median,20.7 and 18.7 mo in TIPS and ET groups,respectively),rebleeding from any source occurred in 11 patients in the TIPS group as compared with 31 patients in the ET group(Kaplan-Meier analysis and log-rank test,P = 0.000).Rebleeding rates at any time point(6 wk,1 year and 2 year) in the TIPS group were lower than in the ET group(Bonferroni correction α' = α/3).Eight patients in the TIPS group and 16 in the ET group died with the cumulative survival rates of 80.6% and 64.9%(Kaplan-Meier analysis and log-rank test c2 = 4.864,P = 0.02),respectively.There was no significant difference between the two groups with respect to 6-wk survival rates(Bonferroni correction α' = α/3).However,significant differences were observed between the two groups in the 1-year survival rates(92% and 79%) and the 2-year survival rates(89% and 64.9%)(Bonferroni correction α' = α/3).No significant differences were observed between the two treatment groups in the occurrence of hepatic encephalopathy(12 patients in TIPS group and 5 in ET group,KaplanMeier analysis and log-rank test,c2 = 3.103,P = 0.08).The average total cost for the TIPS group was higher than for ET group(Wilcxon-Mann Whitney test,52 678 RMB vs 38 844 RMB,P < 0.05),but hospitalization frequency and hospital stay during follow-up period were lower(Wilcxon-Mann Whitney test,0.4 d vs 1.3 d,P = 0.01;5 d vs 19 d,P < 0.05).CONCLUSION:Early use of TIPS is more effective than endoscopic treatment in preventing variceal rebleeding and improving survival rate,and does not increase occurrence of hepatic encephalopathy.Hui Xue Meng Zhang Jack XQ Pang Fei Yan Ying-Chao Li Liang-Shan Lv Jia Yuan Muna Palikhe Wei-Zhi Li Zhi-Lun Wang 2012World Journal of Gastroenterology2012,18,48:17
8An efficient method to synthesize HMX by nitrolysis of DPT with N_2O_5 and a novel ionic liquid显示文摘A novel polyethylene glycol(PEG)-200-based dicationic acidic ionic liquid(PEG_(200)-DAIL) was used to synthesize HMX from DPT by nitrolysis with N_2O_5.It was found that either N_2O_5 or PEG_(200)-DAIL could improve the yield.Furthermore,the combined use of PEG_(200)-DAIL and N_2O_5 could increase the yield of HMX to 64%with the used quantity of HNO_3 decreased dramatically.Hui Zhen Zhi Jun Luo Guang An Feng Chun Xu Lv 2009Chinese Chemical Letters2009,20,4:15
9Electroacupuncture promotes the recovery of motor neuron function in the anterior horn of the injured spinal cord显示文摘Acupuncture has been shown to lessen the inflammatory reaction after acute spinal cord injury and reduce secondary injury.However,the mechanism of action remains unclear.In this study,a rat model of spinal cord injury was established by compressing the T8–9 segments using a modified Nystrom method.Twenty-four hours after injury,Zusanli(ST36),Xuanzhong(GB39),Futu(ST32)and Sanyinjiao(SP6)were stimulated with electroacupuncture.Rats with spinal cord injury alone were used as controls.At 2,4 and 6 weeks after injury,acetylcholinesterase(ACh E)activity at the site of injury,the number of medium and large neurons in the spinal cord anterior horn,glial cell line-derived neurotrophic factor(GDNF)m RNA expression,and Basso,Beattie and Bresnahan locomotor rating scale scores were greater in the electroacupuncture group compared with the control group.These results demonstrate that electroacupuncture increases ACh E activity,up-regulates GDNF m RNA expression,and promotes the recovery of motor neuron function in the anterior horn after spinal cord injury.Jian-hui Yang Jian-guo Lv Hui Wang Hui-yong Nie 2015Neural Regeneration Research2015,10,12:15

12Serum N-glycan markers for diagnosing liver fibrosis induced by hepatitis B virus显示文摘BACKGROUND Hepatitis B virus (HBV) infection is the primary cause of hepatitis with chronic HBV infection,which may develop into liver fibrosis,cirrhosis and hepatocellular carcinoma.Detection of early-stage fibrosis related to HBV infection is of great clinical significance to block the progression of liver lesion.Direct liver biopsy is regarded as the gold standard to detect and assess fibrosis;however,this method is invasive and prone to clinical sampling error.In order to address these issues,we attempted to find more convenient and effective serum markers for detecting HBV-induced early-stage liver fibrosis.AIM To investigate serum N-glycan profiling related to HBV-induced liver fibrosis and verify multiparameter diagnostic models related to serum N-glycan changes.METHODS N-glycan profiles from the sera of 432 HBV-infected patients with liver fibrosis were analyzed.Significant changed N-glycan levels (peaks)(P <0.05) in differentfibrosis stages were selected in the modeling group,and multiparameter diagnostic models were established based on changed N-glycan levels by logistic regression analysis.The receiver operating characteristic (ROC) curve analysis was performed to evaluate diagnostic efficacy of N-glycans models.These models were then compared with the aspartate aminotransferase to platelet ratio index (APRI),fibrosis index based on the four factors (FIB-4),glutamyltranspeptidase platelet albumin index (S index),GlycoCirrho-test,and GlycoFibro-test.Furthermore,we combined multiparameter diagnostic models with alanine aminotransferase (ALT) and platelet (PLT) tests and compared their diagnostic power.In addition,the diagnostic accuracy of N-glycan models was also verified in the validation group of patients.RESULTS Multiparameter diagnostic models constructed based on N-glycan peak 1,3,4and 8 could distinguish between different stages of liver fibrosis.The area under ROC curves (AUROCs) of Model A and Model B were 0.890 and 0.752,respectively differentiating fibrosis F0-F1 from F2-F4,and F0-F2 from F3-F4,and surpassing other serum panels.However,AUROC (0.747) in Model C used for the diagnosis of F4 from F0-F3 was lower than AUROC (0.795) in FIB-4.In combination with ALT and PLT,the multiparameter models showed better diagnostic power (AUROC=0.912,0.829,0.885,respectively) when compared with other models.In the validation group,the AUROCs of the three combined models (0.929,0.858,and 0.867,respectively) were still satisfactory.We also applied the combined models to distinguish adjacent fibrosis stages of 432patients (F0-F1/F2/F3/F4),and the AUROCs were 0.917,0.720 and 0.785.CONCLUSION Multiparameter models based on serum N-glycans are effective supplementary markers to distinguish between adjacent fibrosis stages of patients caused by HBV,especially in combination with ALT and PLT.Xi Cao Qing-Hua Shang Xiao-Ling Chi Wei Zhang Huan-Ming Xiao Mi-Mi Sun Gang Chen Yong An Chun-Lei Lv Lin Wang Yue-Min Nan Cui-Ying Chen Zong-Nan Tan Xue-En Liu Hui Zhuang 2020World Journal of Gastroenterology2020,26,10:12
13Climate change and glacier area variations in China during the past half century显示文摘Glacier variations in the Tibetan Plateau and surrounding mountain ranges in China affect the livelihood of over one billion people who depend on water from the Yellow, Yangtze, Brahmaputra, Ganges and Indus rivers originating in these areas. Based on the results of the present study and published literature, we found that the glaciers shrank 15.7% in area from 1963 to 2010 with an annual area change of -0.33%. The shrinkage generally decreased from peripheral mountain ranges to the interior of Tibet.The linear trends of annual air temperature and precipitation at 147 stations were 0.36°C(10a)^(-1) and 8.96 mm(10a)^(-1) respectively from 1961 to 2010. The shrinkage of glaciers was well correlated with the rising temperature and the spatial patterns of the shrinkage were influenced by other factors superimposed on the rising temperature such as glacier size, type, elevation, debris cover and precipitation.TIAN Hong-zhen YANG Tai-bao LV Hui LI Cheng-xiu HE Ying-bin 2016Journal of Mountain Science2016,13,8:9
14Regulating Effects of Novel CpG Chitosan-nanoparticles on Immune Responses of Mice to Porcine Paratyphoid Vaccines显示文摘Objective To study the regulating effects of a novel CpG oligodeoxynuleotide and the synergistic effect of chitosan-nanoparticles (CNP) with CpG on immune responses of mice, which were used to develop a novel immunoadjuvant to boost immune response to conventional vaccines. Methods A novel CpG ODN containing 11 CpG motifs was synthesized and its bioactivities to stimulate the proliferation of lymphocytes of pig in vitro were detected. Then it was entrapped with CNP prepared in our laboratory by the method of ionic cross linkage, and immunized Kunming mice were co-inoculated with paratyphoid vaccine. The peripheral blood was collected weekly from the tail vein of inoculated mice to detect the contents of IgG, IgA, IgM, and specific antibody against salmonella as well as the levels of interleukin-2 (IL2), IL-4, and IL-6 by SABC-ELISA assay. The numbers of leucocytes, monocytes, granuloytes, and lymphocytes were calculated separately using the routine method. The experimental mice were orally challenged with virulent salmonella 35 days after inoculation. Results This CpG ODN could remarkably provoke the proliferation of lymphocytes of pig in vitro in contrast with the control (P<0.05). Compared with those of the control, immunoglobulins, including IgG, IgA, IgM, and specific antibodies to paratyphoid vaccine, increased significantly in sera from the CpG or CpG-CNP-vaccinated mice (P<0.05). IL-2, IL-4, and IL-6 increased remarkably in sera from immunized mice (P<0.05). The leucocytes, monocytes, granuloytes, and lymphocytes of the mice immunized with CpG or CpG-CNP were also increased in number (P<0.05). After the challenge, these immunity values were elevated in the mice vaccinated with CpG or CpG-CNP. The immunized mice all survived, while the control mice fell ill with evident lesions with diffuse hemorrhage in stomach, small intestine, and peritoneum. Conclusions CpG ODN entrapped with CNP is a promising effective immunoadjuvant for vaccination, which promotes humoral and cellular immune responses, enhances immunity and resistance against salmonella by co-administration with paratyphoid vaccine.MAN-LIANG FU SAN-CHENG YING MEI WU HUI LI KAI-YUAN WU YI YANG HUAN ZHANG CHI CHENG ZE-ZHOU WANG XIU-YING WANG XUE-BING LV YI-ZHENG ZHANG RONG GAO 2006Biomedical and Environmental Sciences2006,19,4:8
15Nasopharyngeal adenoid cystic carcinoma: magnetic resonance imaging features in ten cases显示文摘Nasopharyngeal adenoid cystic carcinoma (NACC) is a rare malignancy with high local invasiveness. To date, there is no consensus on the imaging characteristics of NACC. To address this, we retrospectively reviewed 10 cases of NACC and summarized the magnetic resonance imaging (MRI) features. MR images of 10 patients with histologically validated NACC were reviewed by two experienced radiologists. The location, shape, margin, signal intensity, lesion texture, contrast enhancement patterns, local invasion, and cervical lymphadenopathy of all tumors were evaluated. Clinical and pathologic records were also reviewed. No patients were positive for antibodies against Epstein-Barr virus (EBV). The imaging patterns of primary tumors were classified into two types as determined by location, shape, and margin. Of all patients, 7 had tumors with a type 1 imaging pattern and 3 had tumors with a type 2 imaging pattern. The 4 tubular NACCs were all homogeneous tumors, whereas 3 (60%) of 5 cribriform NACCs and the sole solid NACC were heterogeneous tumors with separations or central necrosis on MR images. Five patients had perineural infiltration and intracranial involvement, and only 2 had cervical lymphadenopathy. Based on these results, we conclude that NACC is a local, aggressive neoplasm that is often negative for EBV infection and associated with a low incidence of cervical lymphadenopathy. Furthermore, MRI features of NACC vary in locations and histological subtypes.Xue-Wen Liu Chuan-Miao Xie Hui Li Rong Zhang Zhi-Jun Geng Yun-Xian Mo Jing Zhao Mu-Yan Cai Yan-Chun Lv Pei-Hong Wu 2012Chinese Journal of Cancer2012,31,1:8
16Nucleic acid detection in the diagnosis and prevention of schistosomiasis显示文摘Schistosomiasis is an important zoonotic parasitic disease that causes serious harms to humans and animals.Surveillance and diagnosis play key roles in schistosomiasis control,however,current techniques for surveillance and diagnosis of the disease have limitations.As genome data for parasites are increasing,novel techniques for detection incorporating nucleotide sequences are receiving widespread attention.These sensitive,specific,and rapid detection methods are particularly important in the diagnosis of low-grade and early infections,and may prove to have clinical significance.This paper reviews the progress of nucleic acid detection in the diagnosis and prevention of schistosomiasis,including such aspects as the selection of target genes,and development and application of nucleic acid detection methods.Ping He Lan-gui Song Hui Xie Jin-yi Liang Dong-ya Yuan Zhong-dao Wu Zhi-yue Lv 2016Infectious Diseases of Poverty2016,5,1:8

18Implications of biomarkers in human hepatocellular carcinoma pathogenesis and therapy显示文摘Hepatocellular carcinoma(HCC)is one of the most frequent tumors worldwide and accounts for approximately one-third of all malignancies.In the past decade,advances have been made to improve the prognosis of HCC,including improvement in the clinical diagnosis of early-stage HCC using molecular biomarkers and molecular-targeted therapy to treat advanced HCC.However,the diagnosis,pathogenesis and targeted therapy of HCC are not completely independent,and should be comprehensively studied.For example,a number of tumor markers provide useful clinical information not only for prognosis,but also in pathogenesis and treatment efficacy.Therefore,this review will focus on the role of several specific biomarkers implicated in the pathogenesis of HCC and several promising molecular-targeted drugs that target the biomarkers of HCC.Li-Li Han Yi Lv Hui Guo Zhi-Ping Ruan Ke-Jun Nan 2014World Journal of Gastroenterology2014,20,30:7
19Association of genotypes of rs671 within ALDH2 with risk for gastric cardia adenocarcinoma in the Chinese Han population in high-and low-incidence areas显示文摘Objective: This study aimed to determine if gastric cardia adenocarcinoma(GCA) risk was associated with the lys(A or *2) allele at the rs671(glu504lys) polymorphism within the aldehyde dehydrogenase 2(ALDH2) gene in a Chinese Han population. We also aimed to investigate ALDH2 genotypic distributions between subjects from high- and low-incidence areas for both GCA and esophageal squamous cell carcinoma(ESCC).Methods: We designed a case-control study including 2,686 patients with GCA and 3,675 control subjects from high- and lowincidence areas for both GCA and ESCC in China. Taq Man allele discrimination assay was used to genotype the rs671 polymorphism. χ~2 test and binary logistic regression analysis were used to estimate the odds ratios for the development of GCA,and multivariate ordinal logistic regression was used to analyze ALDH2 genotypic distributions among different groups.Results: Compared with ALDH2*1/*1 homozygotes, ALDH2*1/*2 and ALDH2*2/*2 carriers did not increase the risk for GCA in the Chinese Han population(P>0.05). Interestingly, the ratio of homozygous or heterozygous ALDH2 *2 carriers in highincidence areas for both GCA and ESCC was lower than that in low-incidence areas(P<0.001).Conclusions: Genotypes of rs671 at ALDH2 may not increase GCA susceptibility in Chinese Han populations. In addition, the ALDH2 genotypic distribution differs between Chinese Han populations from high- and low-incidence areas for both GCA and ESCC. Our findings may shed light on the possible genetic mechanism for the dramatic geographic differences of GCA occurrence in China.Lian-Qun Zhang Xin Song Xue-Ke Zhao Jia Huang Peng Zhang Lu-Wen Wang Hui Meng Jian-Wei Ku Guo-Qiang Kong Tao Jiang Xin-Min Li Xiao-Long Lv Teng Ma Guo Yuan Min-Jie Wu Shou-Jia Hu Shuang Lv Tang-Juan Zhang Ling-Fen Ji Zong-Min Fan Neng-Chao Wang Yao-Wen Zhang Fu-You Zhou Li-Dong Wang 2017Cancer Biology & Medicine2017,14,1:7
20Anti-hyperglycemic effects of dihydromyricetin in streptozotocin-induced diabetic rats显示文摘Dihydromyricetin(DHM),as a bioactive flavanonol compound,is mainly found in“Tengcha”(Ampelopsis grossedentata)cultivated in south of China.This study aimed to investigate the anti-hyperglycemic and antidyslipidemic activities of DHM using type 2 diabetes mellitus(T2D)rats,which was induced by feeding with high fat and fructose diet for 42 days and intraperitoneal administration of streptozocin.Forty-eight freshlyweaned rats were randomly assigned into the negative control(Blank),low dose(100 mg/kg),medium dose(200 mg/kg),high dose(400 mg/kg),and positive(40 mg/kg,met)groups.Fasting blood glucose and body weight were measured at weekly interval.Oral glucose tolerance tests were performed on days 42.The results revealed that DHM possessed significant antihyperglycaemic and antihyperinsulinemic effects.Moreover,after the DHM treatment,p-Akt and p-AMPK expression was upregulated,and glycogen synthase kinase-3β(GSK-3β)expression was downregulated,indicating that the potential anti-diabetic mechanism of DHM might be due to the regulation of the AMPK/Akt/GSK-3βsignaling pathway.Maojun Yao Hui Teng Qiyan Lv Huifang Gao Tengming Guo Yiwen Lin Sihai Gao Meihu Ma Lei Chen 2021Food Science and Human Wellness2021,10,2:6
